4X77B00032-ACC Accortec 64GB PC5-44800 288-pin DDR5 SDRAM RDIMM

4X77B00032-ACC Overview

The high-density 64GB DDR5-5600MHz (PC5-44800) ECC Registered RDIMM from Accortec, engineered as a 100% guaranteed compatible alternative to the Lenovo factory original part (4X77B00032). Operating at a power-efficient 1.1V, this 288-pin enterprise server module features an onboard register to buffer command signals, drastically reducing the electrical load on the CPU’s memory controller to ensure absolute stability in multi-DIMM configurations.
Specifically optimized for next-generation Lenovo ThinkSystem servers and ThinkStation workstations, the module integrates an onboard Power Management Integrated Circuit (PMIC) for precise, local voltage regulation and superior power efficiency. It also features a dual-layer error-correction architecture combining hardware-level sideband ECC with native On-Die ECC—to eliminate single-bit data errors and prevent system downtime.
